Police seize drugs shaped as 'Pez' lollies

Pills shaped like `Pez' lollies that contain a potent opiate have been seized by West Australian police.

The multicoloured pills contain acetyl fentanyl, which has not previously been seen in a tablet form, a spokesman for the serious and organised crime division said on Friday.

"Users have no guarantees about what they are consuming when they are consuming illicit drugs," he said.

Police seized 180 of the lolly-shaped drugs last month and advise anyone in possession of the pills to not take them and destroy them immediately.
